Firefox 21 for Windows, Mac, and Linux out; official launch is today

Firefox 21 is due to officially launch Today, but you can grab the desktop version now from Mozilla’s servers via FTP.

For those who prefer to wait for the official launch, keep your browser pointed toFirefox.com. Soon after it arrives tomorrow, Mozilla will also push it out via the browser’s automatic updates.

There’s no official Firefox 21 changelog as of yet, but the beta release notes should serve as a decent guideline (remember that features are sometimes added or removed before the stable version is released):
